Penny Arcade Expo attendees were treated to the very first footage of Metal Gear Solid: Ground Zeroes. Running on a PC with specs comparable to current-gen consoles, Ground Zero is the first game to show off Kojima Productions' new Fox Engine--and boy, is it a beaut.

Watch this ten-minute debut trailer to see Fox Engine show off its shaders, and impressive lighting and particle effects. The game is currently announced for PlayStation 3 and Xbox 360.

Ground Zeroes promises to be an open-world game, one that will let you deploy a flare at any time to call in a helicopter--one that will let you fly between missions and even other countries. There are many vehicles that can be commandeered as well--all part of Kojima's plan to create a "game without game over."

Oddly, Ground Zeroes is not Metal Gear Solid 5, according to a transcript by the PlayStation.Blog. Instead, it's a "prologue" to whatever MGS5 will end up being. However, given the significant advancement in tech Ground Zeroes represents, we're certain it'll be as important as any numbered entry in the franchise.
